1920s French Art Deco 3.25 Carat Diamond Geometric Platinum Brooch Pin

Three large old European cut diamonds march across the center in open bezel settings, surrounded by 52 additional old European and single cut diamonds arranged in a geometric composition of stepped pavé, open rectangular cutouts, and fine milgrain borders. A prime example of Jazz Age jewels. At 3.25 carats total and 45mm wide, it's perfect for a lapel, a neckline, or a plain black dress entirely on its own. Platinum throughout and French-made—a wonderful collector's brooch.
